Having just assisted an elderly neighbour liaise with another energy supplier who insist on contact via online chat and email - both alien to someone of 89 & frustrating even for me, it is nothing less than a joy to receive the customer service Octopus offers. You can call them and talk to an agent and responses to emails are swift & helpful. All my issues quickly dealt with by Octopus. Professional. No quibble. No stress. Thank you. Needless to say have advised the elderly neighbour to change energy providers to Octopus. How the elderly unfamiliar with chat, email and smartphone apps are expected to cope is beyond me. Without help they are truly very vulnerable to costly providers.
